Temperature
Global Temperatures are Soaring
Global Temperatures are trending upwards
- The black line shows the “long-term trend” of the “average global air temperatures” from 1880 to 2015 produced by the US National Oceanic and Atmospheric Administration (NOAA)
- The upward trend in
temperature continues after 2015. - Below I describe how you can get the most recent graph.
- Temperatures have increased by 0.67°C per century between 1880 and 2014.
Note: 2016, 2017 & 2018 all hotter than 2015.
The more recent graphs reinforce the message gained from the above 2015 graph. Years 2016, 2017 and 2018 have all been significantly hotter

2014 and 2015 are the hottest years shown here.
- Each “temperature anomaly” is the temperature difference from the average temperature shown in degrees Fahrenheit.
- The average global temperature anomaly for each year is shown by a rectangle:
- The blue rectangles show temperatures below the average
- The red rectangles show temperatures above the average
- The hottest year on record was 2015. (See the right-most red rectangle on the graph.)
- The second hottest year was 2014.

The temperature increases are already damaging.
We are already experiencing significant impacts of this warming:
- Hotter weather with extended fire seasons
- Droughts, bush-fires and floods are more frequent and intense
- The distribution of plants and animals is shifting towards the poles,
- The planet is losing ice
- The oceans are rising faster
It is not sustainable for us to have global temperature increasing like this.
